As part of their cuts Monday, the Rangers released veterans Conor Jackson, Joe Beimel and Mitch Stetter, making the group free agents.

Jackson, who finished last season with the Red Sox, was vying to make the Rangers as a right-handed hitting option at first base and in the outfield corners, but he was just 3-for-33 this spring. The poor showing suggests that he’ll have to go to Triple-A for a bit to earn another shot. The Nationals are one team that may want to give him a look, considering they have Adam LaRoche and Michael Morse banged up and the fragile Mark DeRosa as their top fallback at first base.

Beimel and Stetter were among those vying to become the lone lefty in the Texas pen. Beimel allowed three runs in six innings this spring, while Stetter gave up six runs — two earned — in 3 1/3 innings. The Rangers are still considering Michael Kirkman, Neal Cotts and maybe Robbie Ross for a role, though it’s not guaranteed that they will keep a lefty.

Blue Jays closer Roberto Osuna was arrested in Toronto back on May 8 on charges of assault against a woman and he has been on MLB’s administrative leave list ever since — that leave having been extended twice already.

Canadian authorities aren’t revealing any details about the case so as to protect the identity of the accuser and it’s unclear where MLB’s investigation into the matter stands at this point, but Jon Heyman of FanRag Sports opens his latest column with this note …

Toronto Blue Jays star closer Roberto Osuna’s domestic issue is said by people familiar with the case to be serious and involve allegations of a physical nature, which would draw a significant ban.

Heyman notes that Major League Baseball handed 15-game suspensions to Jeurys Familia and Steven Wright for domestic assault cases where there was no physical abuse — or none proven — and that Aroldis Chapman got 30 games after a police report revealed that he did get physical with the victim and also fired a gun.

It sounds like Osuna could be facing a suspension of at least 20-25 games, given the precedent. Again, though, we don’t have any actual details.

Tyler Clippard has been operating as Toronto’s primary ninth-inning man in Osuna’s absence.
